Downloading CPGUI 1.3 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. The actual developer of this free Mac application is Binh Nguyen Xuan. We recommend checking the downloaded files with any free antivirus. The program lies within Developer Tools, more precisely Webmaster Tools.
From the developer:
CPGUI is an application that helps you with coding React Native and Microsoft CodePush. The program works without the need to install NPM or React Native or Codepush. The graphic user interface helps you to add, delete, and check the app and its deployment.
You may want to check out more software for Mac, such as Adobe Shockwave, Image2Web or Vista Editor, which might be similar to CPGUI.
